lMPROVEMENT IN STAND-PIPES.

Specification forming part of Letters Patent No. 204,844, dated May 28,1878; application filed March 9, 1878.

have invented a new and useful Improvement in Stand-Pipes; and we dohereby declare the following to be a full, clear, and exact descriptionthereof, reference being had to the accompanying drawing, forming partof this specification, in which-- Figure 1 is an elevation of astand-pipe embodyin g our invention, the valve-pit being shown insection. Fig. 2 is apartial sectional view of the valve-chamber,pedestal, and standpipe. Fig. 3 is an enlarged sectional view of thevalve-chamber and valve. Figs. 4, 5, 6, 7, and 8 are detail views.

Like letters refer to like parts wherever they occur.

Our invention relates to the construction of stand-pipes for supplyingthe tank-water to locomotive-tenders and for like purposes.

We will now proceed to describe our invention, so that others skilled inthe art to which it appertains may apply the same.

E indicates a platform, beneath which is formed a pit or excavation, P,for the valvechamber of a stand-pipe. This excavation is walledsuitably, and floored over just below the platform E, to form anintermediate space, 10, which can be filled with sawdust or likenon-conductor, to guard and protect the valvechamber from lowtemperatures.

A represents a vertical pipe, usually of castiron, one-half inch thickand about eight inches interior diameter, either formed to seat over theupper end of the valve-chamber, or prefer-- ably bolted at its bottom toa flange-pipe, a, which cups over the top of the valve-chamber, aroundwhich it swings freely. In order to reduce the friction as far aspossible, aball-joint or a brass ring, B, is neatly turned to fit and isinserted between the pipes.

Upon the upper end of vertical pipe A is bolted an elbow, A to which issecured a horizontal feed=pipeor jib, A, usually of zinked sheet-iron,and of such length that when swung into position for use its outer endwill hang directly over a track with relation to which the stand-pipeand its platform are located.

Above the platform E, and inclosing vertical pipe A, is a pedestal, D,having a broad firm base, d, through which pass lag-screws to hold it inposition. This pedestal is closed at its top by a cap-plate, F, havingan aperture carefully turned to fit pipe A, which is steadied andguarded against lateral motion by said capplate.

0 indicates a hand-wheel, which may be cast in two pieces, and boltedtogether around pipe A in a slotted flange, 0, just above pedestal D,and at a convenient distance above platform E to permit the pipe A to beoperated therefrom, so as to turn the pipe and its jib in any requireddirection.

G represents the valve chamber, located within pit P; and G, thewater-supply pipe.

Within the valve-chamber G is the valve, formed of two plates, H H,(usually brass disks,) properly beveled on the edges to fit seats H H,the plates H being joined centrally by a tube, J, and stiffened by threeor more wings, S S. Through the center of tube J passes the valve rod orstem,R, having a flange or shoulder, 1, above the upper valve-plate H,and a threaded nut, 0, below the lower plate, for securing the valve tothe rod. The rod It, below the valve, is reduced in size, and carries asmaller valve, h, adapted to close an opening in the bottom of thevalve-chamber when the rod R is raised, and to open the same when thevalve-rod is lowered, thus permitting the escape of the residuary orsurplus water, which would otherwise be retained and freeze within thestand-pipe. In order to adjust this supplemental valve to the variedlift of valve-rod B, it will preferably be secured thereto by jamnuts orlike devices, and should terminate above in a sleeve, h, which entersthe opening in the bottom of the valve-chamber, and prevents loss ofwater when the valve is insufliciently lifted. On the upper end ofvalve-rod R is an eccentric-band, vV, preferably adjustably connectedthereto by the thread to and key k, so that by screwing the rod eitherup or down, (and fastening it by key 76,) the lift of the valve may beregulated at pleasure.

V is a rod, supported in bearings or standards v on the jib orfeed-pipe, and furnished at its outer end with a hand-lever, N. Upon ornear the opposite end of rod Y is an eccentric or earn, K, which workswithin the band V on the upper end of valve stem or rod R, so that bymeans of lever N the rod "V maybe turned to bring the greatesteccentricity of K uppermost when it is desired to open valve H H. Inorder to protect the cam or eccentric K, a hollow chamber, Y, of anydesired shape, is formed on the elbow A in direct line with thevalve-stem It; and in order to get at the cam and rod for oiling andadjusting the parts, the can] chamber is closed by a removable cap, Y.

Secured to the elbow of the stand-pipe, at a point opposite thefeed-pipe or jib, is a counterpoise, M, arranged on a rod, and providedwith a set-screw, X, so that the weight can be moved backward andforward, and finally secured in such position as will counterbalance theweight of the feed-pipe or jib, and prevent the vertical column A frombinding or cramping at joint B or on cap-plate F as it is swung around.

As before specified, the ring B, valveplates H H, and ringseats H II arepreferably of brass; but other suitable material well known in the artmay be employed.

In lieu of the rod extending along the jib or feed-pipe, the eccentric Kmight be operated by a short shaft and rope or chain carried to theouter end of the jib.

The operation of our devices is as follows: The platform and verticalpipe A being properly located with reference to the track, and thecalculated length of the jib or feed-pipe being such that its outer endwill swing directly over the center of the track, or man-hole in atender thereon, the vertical pipe A is rotated on the valve-chamber bymeans of handwheel C until the end of feed-pipe is in position over theman-hole of the tender. This brings the lever N in reach of a personupon the tender, who can thus operate the valve H H while watching thewater in the tender, thus guarding again st an overflow. By adj ustingthe stem and eccentric so as to lift. the valve-stem two inches, boththe upper and lower plates of the valve will rise that distance, makingan aperture of water-way of two inches above and two lnches below, thusperforming the same service as a single valve would if raised twice thisdistance.

Having thus described our invention, what we claim, and desire to secureby Letters Patent is- 1 In combination with a stand-pipe, the valvechamber provided with the doubleseated valve, substantially as and forthe purpose specified.

2. The combination, with the valve H and its stem, of the eccentric-hand\V, eccentric K, and rod V, mounted on the jib, the whole constructedsubstantially as and for the purpose specified.

3. The combination, in a stand-pipe, of the valve-stem, theeccentric-band adjustably connected to the valve-stem, and the cam oreccentric, substantially as and for the purpose specified.

4. In a stand-pipe,the combination of the main valve and the adjustablefrost or waste valve, provided with the sleeve h, connected to andoperated from the main valve or its stem, substantially as and for thepurpose specified.

In testimony whereof we, the said EDWARD LEWIS and W. A. MALONEY, havehereunto set our hands.
